The Card Logic Logarithm as an Interactive Media in Teaching Logarithm: A Development Study

Abstract

This study aimed to develop an interactive media namely card logic logarithmic (CLL) that are valid, practical and have the potential effect of increasing student interest and learning outcomes in learning logarithm in Senior High School. The developmental research method by Van den Akker used in this study, with a formative evaluation by Martin Tessmer. The Jan Van Den Akker's method consists of three stages, namely preliminary research, prototyping stage, and formative evaluation. Based on the results, it was found that: (1) the CLL media have been produced for teaching logarithm which are valid, practical, and effective; (2) the CLL media have been assessed by validators with a validity value of 4.54 with a valid category; (3) the CLL media have been assessed by validators with a practical value of 4.28 in the very high category; and (4) the CLL media in the aspect of effectiveness based on the learning outcomes test showed 87.1% of students scored above the standard.
